Framework agreement for deodorization units

In Denmark, the amount of biogas in the distribution grids increases. When bio natural gas (biomethane) from distribution grids is fed into the transmission grid, the concentration of odorant present in the gas needs to be reduced to accepted trace amounts max (1.0 mg THT/Nm3) before the gas enters the transmission grid. The removal of the odorant, tetrahydrothiophene (THT), will be executed by a deodorization unit, at the place of injection into the transmission system. Through the establishment of the present framework agreement, the Contracting Authority wants to purchase a number of deodorizing units for injection of upgraded biogas from the distribution grid into the natural gas transmission grid in Denmark. Deodorization units for reduction of odorant (THT) in the source gas has to the requirements of the export grids will be included in the reverse flow plant’s facilities. The capacity is within 3.500 Nm3/hr., to 9.500 Nm3/hr., and maximum inlet pressure 19-40 barg. The exception is 3.C which is 17.300 Nm3/hr. and 19 barg. The total purchase is made for a period of 4 year(s) from the signing of the framework agreement with the option of an extension for 2x2 years. Orders under the framework agreement will be allocated directly to the supplier which, in the view of the Contracting Authority, has submitted the most economically advantageous tender, see section 4.1. The estimated consumption during the term of the framework agreement is expected to amount to (7) deodorizing units in total. The estimated number of deodorizing units is one of each of the following (ID 1, ID 2, ID 3.b, ID 3.c, ID 4, ID 6, and ID 7). The framework agreement consists of an estimated consumption for the FTB project of six (6) deodorizing units. This framework agreement consists of an initial call-off for four (4) deodorizing units (ID 2, ID 3.b or ID 3.c, ID 6 and ID 4), which will be awarded on the basis of the award of the framework agreement to the tenderer that achieves the highest score, cf. section 4.2. Further, two (2) deodorizing units are expected to be ordered after the first order, which it expected to be (ID 1 and ID 7). The consumption figures are estimates only and are consequently not binding for the Contracting Authority. The Contracting Authority is not obligated to purchase solely from the framework agreement and may in connection with single-standing purchases choose to tender these independently.
